BALL-CONTAINER FOR BALL-BEARINGS.

Be it knownthat I, JOHN O. BURKLUNI), a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth ofMassachu'setts, have invented anew and useful Improvement in Ball-Containers for Ball-Bearings, of which the following is a specification accompanied by drawings, forming a part of the same.

The "object of my'present invention is to provide a container for holding balls in a all bearing, capable of being constructed from the ball bearing.

Fig. 2 represents a blank from which the container is constructed, as hereinafter described.

Fig. 3 represents the blank having a se-.

ries of concave recesses formed for the re cc tion of the balls.

ig. 4 is an edge view of a portion of the bla-Bk showing three of the ball receptacles open in position to receive the balls.

Fig. 5 is an edge view of the contalner in itscompleted form.

Fig. 6 is a transverse sectional V ew through one of the ball receptacles, showing a ball held therein.

Fig. 7Jis a sectional view through the container, on the plane of the broken line 7-7, Fig. 5.

Fig,' 8 is a longitudinal sectional v ew through one of the ball receptacles, showing a ball lield therein. Similar reference characters refer to similar parts throughout the different figures.

The blank from which. my .ball container is formed is punched from a single piece of.

' sheet metal, as represented in Fig. 2, and it consists of an annular band 1 havingprojecting from the outer edge thereof a series At the ends of the wing of wing pieces 2.

therefrom are and cxtem'ling laterally prongs b, ,3, for the purpose hereinafter described. The blank form. as represented in Fig. *2, is then shaped by appropriate unches and dies into the form shown in 3, in which the annular band 1 1s Specification of Letters Patent.

stamped at regular intervals to form a. ser es of concave recesses 4t, and the Wing pleces 2 are similarly shaped to form a recess 5 for the bal.

During this op aration of forming the-recesses 4 and 5 tie prongs 3, 3, are turned down at right at gles to the wing pieces 2.

The wing pieces 2 are next folded on. the broken hues 6 against the side of the annular band 1. The wing pieces are then bent so they stand at right angles to the annular band 1, as represented in Fig. 4. When the balls have been placed in position in the recesses 4, the wing pieces 2 are bent over the balls as shown in Fig. 5, each ball bein held 1n the space inclosed by the recesse portions 4 and 5, with the prongs 3 extending over the edges of the annular band 1. The tips of the prongs are then turned down against the annular band, as shown at 7, Fig. 7.

Each of the balls is then inclosed in a cage formed by the recesses 4 and 5. The width of the recessed pc rtions 4 and 5 being greater than the diameter of the balls, causes the balls to be held tierein and to slightly project, as shown at 8, 8, Figs. 1 and 6, beyond the edges of the holder so as to bear upon the opposite faces of the ball track.

My improved container is not only made from a single 11h ice but is constructed with but few operations, and avoids the necessity of separatel riveting the pieces together.

I claim,

1. A ball container, formed from an integral blank and comprising an annular band having wing pieces connected at one end .to the outer edge of said band, said annular band having a series of concave recesses, and each of said wings having a concave recess'midway beiwcen itsends, with said 3. A ball container, comprising an annulax band having a series of spaced recesses wlncgl pieces integral at one end with sai ban and means for uniting the op osite ends of said wings with said annular and.-

4. A ball container comprising an annular band, having wing pieces extendin from its outer edge and connected at their free ends withsaid band, and concave recesses in said band and in said wing pieces forming spherically shaped receptacles for the 10 reception of balls, said receptacles having 1 openings to permit the contact of the balls with ball tracks. 1 Dated this fourth day of May 1916. l JOHN O. BURKLUND.
